That is so amazing and goes with the theory put forth in the book On Intelligence (by Jeff Hawkins). The theory is that the mind noticies things that are out of place. If it is too close to an existing pattern, brain will put it into that pattern. To stabd out the new item/concept has to be far enough from any existing pattern. So if a dish is salty and not salty at the same time, it doesnt fit in any of two patterns familier to the brain.
